Product Info

The shift fork is a crucial transmission component — the higher its precision, the smoother and more durable the gear shifting performance. This article compares CNC machining and forging processes to help you select the most suitable manufacturing method for automotive applications.

The shift fork controls the movement of the synchronizer or gear in a transmission system. Even slight deviations can cause noise, excessive wear, or gear failure. Therefore, a highly precise and robust manufacturing process is essential.

■ Shift Fork Production with CNC
● Highlights
・ Uses computer-controlled CNC machines for high precision, with tolerances as tight as ±0.01 mm.
・ Ideal for prototypes or small production volumes.
・ Easy to modify designs, offering great flexibility and quick adjustments.

■ Shift Fork Production with Forging
● Highlights
・ Creates a very strong material structure, providing excellent impact and wear resistance.
・ Standard tolerances are around ±0.1 to ±0.3 mm; additional machining or grinding can achieve tighter tolerances.
・ Lower cost per piece in mass production, making it ideal for large-scale manufacturing.

■ CNC vs Forging: Key Comparison
・ Precision: CNC is best for high-accuracy applications.
・ Strength: Forging excels in durability and impact resistance.
・ Flexibility: CNC allows easy design changes and fast iteration.
・ Production volume: CNC suits small batches or prototyping; forging is preferred for high-volume runs.
